Description

Technical Field

[0001] The present invention relates to the technical field of edge banding machines, and more particularly to a glue pot device of an edge banding machine. Background Art

[0002] Edge banding is an important process in the manufacturing process of panel furniture. The quality of edge banding directly affects the quality, price and grade of the product. The edge banding process of wooden boards includes a series of processes such as pre-milling, preheating, gluing and edging, front and back trimming, rough trimming, fine trimming, scraping, grooving, polishing, etc. First, the gluing device applies glue to the edge of the board and one side of the edge banding tape, and then presses the edge banding tape and the edge of the board together so that the edge banding tape and the edge of the board are firmly bonded together. The glue pot is located above the workbench, and the board moves forward from the bottom of the glue pot. The glue on the roller surface is taken away by the board when it passes through the glue roller to achieve gluing. Since different boards or different furniture have different requirements for glue thickness when edge banding, the existing edge banding machine glue pot device has no quantitative value when adjusting the glue thickness. It can only be adjusted by trial and error based on experience, which is troublesome and time-consuming.

[0003] In the prior art, there is a gluing mechanism for an edge banding machine with a glue quantity regulator, which includes a base, a gluing unit, and a glue quantity regulator. The base includes a glue barrel. The gluing unit is rotatably mounted on the base's glue barrel and includes a glue shaft and an oblique gluing member connected to the glue shaft. The glue quantity regulator is rotatably mounted on the base. The glue quantity regulator includes a glue door shaft, an adjustment plate connected to the glue door shaft, and a baffle. The adjustment plate can simultaneously contact the glue unit with the end edge of the adjustment plate as the glue door shaft rotates, and the baffle is fixed to the glue door shaft in a manner spaced apart from the adjustment plate. Through the design of the above-mentioned gluing mechanism, the thickness of the applied glue can be effectively controlled. However, since the distance of the adjustment plate relative to the gluing unit is changed by rotating the glue quantity regulator, the relationship between the rotation angle and the displacement variable is not easy to measure, and the change in glue thickness cannot be observed intuitively. It is also necessary to make adjustments through trial and error based on experience, which increases the workload of workers. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the existing edge banding machine glue pot device in that there is no quantitative value when adjusting the glue coating thickness, and it can only be adjusted by successive tests based on experience, which is troublesome and time-consuming.

[0042] Example 1

[0043] like Figures 1 to 11 The first embodiment of the glue pot device of the edge banding machine of the present invention is shown as follows. Figure 1 As shown, it includes a melting module 100, an adjustment module 200, a gluing module 400 and a supporting module 500. The adjustment module 200 is installed on the melting module 100 to form a replaceable first split part 10. The gluing roller module 400 and the supporting module 500 together form another second split part 20 fixed on the edge banding machine platform.

[0044] In the glue melting module 100, the glue melting module 100 includes a glue pot cover 1001, a glue pot 1002, and a glue melting seat assembly which are arranged in sequence. The glue pot cover 1001, the glue pot 1002, and the glue melting seat assembly are connected in sequence from top to bottom, wherein the glue melting seat assembly includes an upper glue melting seat 1003 and a lower glue melting seat 1004. A glue melting cavity is provided in the glue pot 1002, and a flow channel 1016 is provided at the bottom of the glue melting seat assembly. The flow channel 1016 is provided between the glue pot 1002, the upper glue melting seat 1003, and the lower glue melting seat 1004. The glue flows from the glue melting cavity of the glue pot 1002 through the flow channel 1016 to the lower glue melting seat 1004 from top to bottom. The lower glue melting seat 1004 is provided with a valve assembly at the outlet of the flow channel 1016. The valve assembly includes: The glue door shaft 1005 and the switch wrench 1008 are provided with a plurality of flow holes in sequence along the axis perpendicular to the glue door shaft 1005, and the flow holes are connected with the outlet of the flow channel 1016. The switch wrench 1008 is installed on the top of the glue door shaft 1005, and the glue melting seat assembly is provided with a through hole corresponding to the position of the switch wrench 1008. The switch wrench 1008 passes through the through hole and protrudes out of the glue melting seat assembly. The switch wrench 1008 can move back and forth relative to the glue melting seat assembly; the glue door shaft 1005 is rotatably connected to the glue melting seat assembly, and the upper end of the glue door shaft 1005 is provided with a door shaft sealing gasket 1006 and a door shaft copper sleeve 1007, and the lower end of the glue door shaft 1005 is also provided with a glue channel sealing plate 1009, and the glue channel sealing plate 1009 is fixed on the lower glue melting seat 1004. The upper melter 1003 is equipped with a wrench stop slot. Toggling the switch wrench 1008 to the left or right stop position controls the opening and closing of the flow channel 1016 outlet. An upper glue retaining washer 1010 is mounted concentrically with the glue roller assembly 4018 above the lower melter 1004. Positioning sleeves 1011 and connecting screws 1012 are mounted on the left and right ends below. Furthermore, the glue pot 1002, upper melter 1003, and lower melter 1004 are equipped with several heating tubes 1013 for heating and insulation, as well as a junction box 1014 and a male and female connector 1015 that can be quickly connected and disconnected.

[0045] In the adjustment module 200, the adjustment module includes an adjustment component, a glue knife 2001 and a scale 2012; the adjustment component includes a cylinder 2011, a limit screw 2006, a reset top shaft 2007, a spring 2008, and a glue knife slider 2005; the glue knife 2001 is installed on the third groove 10041 on the back side of the lower melt glue seat 1004, and a fixed shaft pin 2003 is installed at the rear end of the glue knife 2001, and a roller 2004 is sleeved on the fixed shaft pin 2003, and a slide groove 20051 is provided on the glue knife slider 2005, and the roller 2004 is stuck in the slide groove 20051 of the glue knife slider 2005 and can roll back and forth in the slide groove 20051, and the glue knife slider 2005 is installed on the fourth groove 10042 on the back side of the lower melt glue seat 1004 and can slide back and forth in the fourth groove 10042. A glue knife cover 2002 is mounted on the outside of glue knife 2001 and is attached to the back of lower glue melt seat 1004. This allows glue knife 2001, mounted in third groove 10041 of lower glue melt seat 1004, and glue knife slider 2005, mounted in fourth groove 10042 of lower glue melt seat 1004, to slide only within their corresponding grooves. A stop screw 2006 is mounted above glue knife slider 2005. A return pin 2007 and a return spring 2008 are housed within stop screw 2006. Return pin 2007 can extend and slide within stop screw 2006 and is pressed against the upper end of glue knife slider 2005 by return spring 2008. Stop screw 2006 passes through lower glue melt seat 1004 and is attached to screw hole 10031 of upper glue melt seat 1003. The upper end of the limiting screw 2006 is also sleeved with a first disc spring 2009 and a locknut 2010. The first disc spring 2009 is compressed between the locknut 2010 and the screw hole 10031 of the upper melt seat 1003. The locknut 2010 is clamped on the side of the connecting screw 1012 and restricted from rotating, thereby automatically pre-tightening the limiting screw 2006. The rubber knife slider 2005 is also connected to the scale 2012. Preferably, the sliding groove 20051 is inclined on the rubber knife slider 2005. The rubber knife slider 2005 drives the rubber knife 2001 to slide in a sliding manner. The movement distance of the rubber knife slider 2005 and the rubber knife 2001 is multiple. The actual scale value of the scale 2012 is magnified by the same multiple value, thereby enabling the scale 2012 to obtain a more accurate indication value. When the cylinder 2011 is pushed out, the upper end of the glue knife slider 2005 touches the bottom end of the limit screw 2006. At this time, the value indicated on the scale 2012 is the glue thickness S value. By turning the limit screw 2006, the size of the glue thickness S can be adjusted.

[0046] The principle of the adjustment module 200 to adjust the glue thickness S is as follows:

[0047] like Figure 8 and Figure 9As shown, at this time, the glue knife slider 2005 is at the lowest end, and the glue coating thickness S is the largest; when the piston rod of the cylinder 2011 is pushed out to drive the glue knife slider 2005 to move upward, since the glue knife slider 2005 is limited to moving up and down in the vertical direction, and the slide groove 20051 is tilted from the upper left to the lower right, during the upward movement of the glue knife slider 2005, the roller 2004 moves along the slide groove from the upper left to the lower right on the slide groove 20051. The roller 2004 moves along the slide groove 20051 and then drives the glue knife 2001 to move toward the direction close to the glue roller assembly 4018, so that the glue coating thickness S is reduced. When the glue knife slider 2005 hits the limiting screw 2006, the glue knife slider 2005 stops. At this time, the value displayed on the scale is the glue coating thickness S. The glue thickness S can be adjusted by adjusting the limit screw 2006 up and down. When the limit screw 2006 moves up, the glue thickness S decreases, while when it moves down, the glue thickness S increases. The increase or decrease in glue thickness S can be visually reflected on the scale 2012. Furthermore, since the glue knife moves horizontally, the relationship between the glue knife's displacement and the glue thickness S is proportional. The scale 20014 follows the movement of the glue knife slider 2005, and the visual numerical scale makes it convenient and quick to adjust the glue thickness S. When the piston rod of the cylinder 2011 is retracted, the reset top shaft 2007 in the limit screw 2006, under the action of the spring 2008, drives the glue knife slider 2005 downward to its lowest position. Simultaneously, the roller moves from the chute to the top of the chute, thereby driving the glue knife 2001 away from the glue roller assembly 4018. At this point, the glue thickness S is at its maximum.

[0048] In the gluing module 400, the gluing module 400 includes a gluing seat assembly 4001 and a gluing roller assembly 4018. The gluing seat assembly 4001 includes an upper gluing seat and a lower gluing seat connected to each other. A plurality of positioning pins 4016 are installed on the top of the upper gluing seat. The positioning pins 4016 protrude from the upper gluing seat. The melting module 400 is plugged into the positioning pins 4016, and the supporting module 500 is threadedly connected to the lower gluing seat; the gluing roller assembly 4018 is inserted into the gluing seat assembly 4001 and is arranged at both ends of the gluing seat assembly 4001; the gluing roller assembly 4018 includes a gluing roller 4002, and the lower end part of the gluing roller 4002 is sequentially sleeved with a lower copper sleeve 4007, a lower sealing gasket 4008, a TC sealing ring 4009, an upper bearing 4010, a lower bearing 4011, The second disc spring 4013, the locking nut 4014 and the connecting nut 4015, the lower copper sleeve 4007 and the lower sealing gasket 4008 are installed on the glue coating seat assembly 4001, the TC sealing ring 4009, the upper bearing 4010 and the lower bearing 4011 are installed in the bearing sleeve 4012 and are installed in the upper glue coating seat 4001 together with the bearing sleeve 4012. The upper end part of the glue coating roller 4002 is sequentially covered with the lower roller sleeve 4006, the middle roller sleeve 4005, the upper roller sleeve 4004 and the fastening nut 4003 from bottom to top. The fastening nut 4003 is the first fastener set at the top of the glue coating roller 4002, and the locking nut 4014 and the connecting nut 4015 are the second fasteners set at the bottom of the glue coating roller 4002, which together install and fasten each roller sleeve and the bearing sleeve 4012. Positioning pins 4016 that match the positioning sleeve 1011 are installed on the left and right ends of the upper side of the gluing seat assembly 4001. The upper gluing seat is also equipped with a lifting guide sleeve 4017, and the lower gluing seat can limit the axial movement of the bearing sleeve 4012.

[0049] The glue door shaft 1005 is controlled in advance by the switch wrench 1008 to close the outlet of the flow channel 1016, and then the melt glue module 1001 is removed from the glue coating seat assembly 4001, which can facilitate the cleaning of the glue coating roller assembly 4018 and the cleaning of the flow channel 1016. The glue pot 1002 can also be directly replaced, which effectively solves the problem of difficult cleaning encountered in the edge banding operation and eliminates the problem of color mixing when changing glue due to incomplete cleaning.

[0050] The upper roller sleeve 4004, the middle roller sleeve 4005 and the lower roller sleeve 4006 are the main gluing parts. Different mesh patterns are set on the outside of the three roller sleeves to meet the gluing needs of the plate. By replacing roller sleeves with different mesh patterns, the requirements of different thicknesses and materials for different mesh patterns can be met; thus, different edge banding operation conditions can obtain appropriate corresponding gluing mesh patterns, thereby obtaining the best edge banding effect.
